If the union is not helping, no attorney is going to touch your case. In my 12 years as a steward, I rarely lost a case. The biggest problem I found when folks came to me was the issue was not a union issue but a company policy issue. All the union can do then is follow the policy. If you really feel you need an attorney, there are lots of labor attorneys out there, you can probably even find one through this site. Good luck.
