On the other hand, a detriment of using a pre-written template is that it may not handle more complex jobs or specific types of contract projects where there are a lot of detailed deliverables. Obviously, a basic form contract is unlikely to cover all the bases for things like international joint ventures, multi-level sales agency relationships, or insurance services. These are agreements where the costs of an attorney are justified.
Another downside to using an employment agreement template is the potential for building inflexibility into your business. In particular, employment law changes may invalidate or make an existing agreement out of date. If you use the same job template for hundreds of employees and the law changes, you may need to go back and have them re-sign new contracts. This would not always benefit the company, though it is a small risk to take to get the significant legal protections afforded by even the simplest of contracts.
