I cannot support this. The right to strike is fundamental and belongs to the workers. The right to strike is even written into the Canadian Charter of Rights and Freedoms. There is no evidence that there has been any problem in the past. It is just that somebody wants to take away their right to strike. There has never been any problem over the last 100 years.
I cannot support such a move just because it came to somebody's mind. You cannot take away the rights of workers just like that.
