Your name is ironic considering the speculation you are producing to explain away the headline that is not supported by the article.
There are several errors of fact in your comment above.
First of all, the Titanic was not a built "by Britain's White Star Line," it was built for "America's White Star Line." By the time the Titanic and her sister ships were commissioned and built, the White Star Line had been absorbed (In 1902) into the International Mercantile Marine Co. (IMM), a large American shipping conglomerate, owned by J.P. Morgan, which was incorporated in New York.
Secondly, you don't just read between the lines when the question asked in the headline is not even addressed in the body of the article. . . nor even hinted at. Do the research. The building of the Titanic is one of the most heavily researched ships ever built. The fact is that the pay records of the company that built the Titanic, Harland and Wolff, are still extant. In fact, Harland and Wolff Heavy Industries is still in business. Those records are accessible to researchers who might care to examine them and IF women were hired to work on building the Titanic or her sister ships, it would be a well known fact.
The following is my speculation: if, as you say, there were a shortage of the skilled riveters during the building of the Titanic, it would have meant that the skilled men who were hired to rivet were worked harder and longer and may have been more likely to say "good enough" before moving on to the next rivet when the first was not really completed properly.
Thanks
