For those not familiar with law:
Strikes and lockouts are just different sides of the same coin. Having both, secures the parity between unions and companies.
Both parties start the dispute at their own risk, e.g.:
- The union has to pay the wages out of their own cash box
- The company will loose turnover and ultimately loose customers
Having one side stripped of their rights, will lead to a dangerous imbalance. Take a look at the UK, after the "Iron Lady" manged to destroy the power of the trade unions for decades...
