+ 0 Votes some food for thought databaseben 2 years ago there are two factors and two ways to look at this: 1) the answer depends if company b is being billed for your services by company a. if they are not, then you don't have an obligation as an employee of company a to perform services to company b. if they are being billed, then "yes" you have an obligation to provide services to company b, especially if your from the "home office". you see, the financial books between company a and company b have to be kept separate and they cannot co-mingle services, products, expenses and revenue. they cannot share resources between them for free, but they can bill and charge each other for services they provide to each other. it might be that its cheaper for company b to ascertain your services instead of hiring a full time employee. 2) if company a is paying your salary and are also authorizing you to provide services to company b, then as an employee you really don't have a choice unless there is a contract between you and company a - especially if the are reimbursing your for mileage to and from company b. on the other hand, company a must think behind closed doors that you are an asset and they are fortunate that you can provide a helping hand to the struggling company b. in conclusion - while company finances isn't in your job description, you may have leverage yourself if you make your supervisors aware that you understand this facet of business and want clarification about your responsibilities. "you can ask them around the water cooler if company b is being billed for your services. if not, then why not and why should you provide services to them,(even though company a is paying for your wages). also ask what will happen to "me" when company b becomes successful?" if you can turn this scenario into a positive one and make them feel you are doing them a favor by helping company b, then you might be able to get them to do you a favor in the future - especially if company b becomes successful (in part because you helped with your expertise) but the above is only based on my generalization of your question. only you have all the details and understand the atmosphere at your organization and how best to play it. however, i hope the above does give you a little bit of additional information to help you play your cards. ultimately, employee or not, the old adage stills applies: "you scratch my back and i'll scratch yours". if you don't have a contract then job security can depend on what the company feels they owe you for scratching their backs.
