Thank you Dinesh on the inputs provided, these have been really informative,
It is true that we have a case of overworking of employees from an account with different projects. This account deals with mainly hardware infrastructure and most of the clients in the client profile we checked for the account were of the types that were extremely cost conscious. In short they needed more work within a lower cost margin.
Thinking of the additional business opportunities that could be taken from each client, though with a small profit margin individually, the company had been overworking the employees and at the same time cutting on costs to maintain the profit margin.
The clients on the other hand finding the skill-set, common in the industry kept on bargaining and threatening to hand over the project to the competition. So, to retain them each supplier company had to oblige accordingly putting the final burden on the employees.
We tried suggesting training on latest technical skills and importing of domain knowledge from outside. But then, there was a budget issue considering the minimal profit margin the project account was getting from each client. At the same time, with the existing employee skill set common in the industry, there was no unique demand and so no incentive for funding from external sources.
In short, it seemed both the employees and the employer and the clients were trapped in, with each other, not allowing the situation to change.
