Manisha,
It is not only the clause of "workman", there are many other points which have to be kept in mind while drafting standing orders, like transfer, abandonment, termination etc. All these clauses should be drafted in consonance with applicable Labour Laws. It will be better for your organization, if you get the standing orders drafted by an expert.
However, the workman will be those employees who fall under the definition of "workman" u/s 2(s) of Industrial Disputes Act 1947, irrespective of their designation.
